bifrost KTH/CSD course kick-off Fall 2010 Robert Olsson

What is bifrost? Small Linux suited for USB For infrastructure For research & education Name of human network and collaboration Why a new Linux distro? We've been around For 15 years soon. What about Red Hat/Debian Ubuntu etc?

For who? Networking people Unix/Linux Needing a small flexible distro Research & Education

Objectives infrastucture? Hardware selection – Crucial Software selection - Crucial Testing - Crucial Bug Fixes/Support Crucial Development - Crucial

Basic functions? Routing Firewalling Login services Traffic logging Gateways etc Virtualization and/or Namespaces (New) Ipv4, ipv6 Network testing pktgen/netperf etc

Routing deamons Packet forwarding is done in Linux kernel But routing protocols is run by userpace Deamons Currently tested versions of quagga Bgp, OSPF both Ipv4, ipv6 Cisco API Of course other software can be used Bird?

More than 10 year in production at Uppsala University Stockholm 2 * XEON 5630 TYAN *10g ixgbe sfp+ LR/SR Full Internet routing via EBGP/IBGP DMZ AS 2834 UU- 1UU- 2 Internera l UU-Net L- green L- red ISP/SUNET AS1653 Local peering In Uppsala ipv4/ipv6 OSPF

R & D related to bifrost Close collaboration with Linux networking Developers and industry NAPI (3 years) now in most network drivers Pktgen testing in linux, fib_trie, (routing algo) routing stats to monitor and understand network Etc, etc

Block hw structure

Cache effect/Performance

Overall Effect Inelegant handling of heavy net loads System collapse Scalabiity affected System and number of NICS A single hogger netdev can bring the system to its knees and deny service to others March 15 report on lkml Thread: "How to optimize routing perfomance" reported by - Linux 2.4 peaks at 27Kpps - Pentium Pro 200, 64MB RAM

Lab testing HW and SW

Not all were selected...

Hardware - NIC Intel 10g board Chipset Open chip specs. Thanks Intel!

KTH/CSD Current focus Optical to Open Source Router Low-Power & Renewable Energy Virtualization/Namespaces Performance Cost

Optical modules Optical sender and receiver in one module SFP 1G XFP 10G SFP+ 10G

DOM - Optical Monitoring Optical modules can support optical link monitoring RX, TX power, temperatuers, alarms etc Newly added support to Bifrost/Linux
